Shedding Concern for my IJ

[RBDTerrell]

Hi all,

I have a 4-5 year old female Irian Jaya that hasn't shed in the last 3-4 months. When I picked her up, a few months back I thought she was getting ready to shed because she looked really dull. I also noticed that the enclosure she came in was incredibly dirty. There was excessive water staining and buildup on the glass. I cleaned it all out and bathed her twice and since then everything has been fine except the scales on her back are really rough and look very dry. Her sides are smooth but her entire spine looks to be very dried out. She eats whenever I offer her food and I mist her every couple of days just like with all of my other carpets. Today I removed her from her old enclosure, bathed her, and relocated her to a tub so I can better monitor her humidity. Is it possible that she retained an entire shed? Has anyone else ever witnessed this? I'll try and get pictures of her this week. Idk if it's a cause for concern matter just yet, but i'd like to get as much info as I can before possibly taking her to the vet. Any help would be appreciated

Thanks
